Study on advancement of CFD technology and utilization of tank test data

National Maritime Research Institute (NMRI) has made efforts in research of CFD (Computational Fluid Dynamics) and has developed various CFD software including Navier-Stokes solvers and pre- and post-processors. These codes have been distributed to the shipbuilding industries in Japan and are being used as practical design tools. In 2002, NMRI established Center for CFD Research in order to enhance CFD research activities and to promote the spread of NMRI's CFD software. Center for CFD Research carried out the research project 'Study on Advancement of CFD Technology and Utilization of Tank Test Data', which was carried out in the fiscal years 2003 and 2004. The project consists of development and enhancement of the CFD software for distribution and the holding of the international workshop on CFD validation, namely, CFD Workshop TOKYO 2005. In addition, the tank tests were performed for a VLCC ship hull in oblique tow conditions to acquire the flow field data for the comparison at the Workshop. In this paper, the outline of the present project is presented.
